Application August 9, 1940, Serial No. 352,012 2 Claims. -(c1. 189- 19) This invention relates to bathing apparatus and more particularly to shower baths.

The primary object of this invention resides in theprovision of a shower bath adapted to be used in army and other camps where a number of individuals may use the same simultaneously.

Another object of this invention resides in the provision of a shower bath adapted to be knocked down and packed in a small space for transportation.

A further object of this invention resides in the provision of a portable shower bath adapted to furnish warm or cold water to individuals using the same.

A still further object of this invention resides in the provision of a shower bath consisting of an assemblage of elements adapted to be dissembled from operative association and reassembled in knock-down relation to form a compact and rigid unit for transportation.

Aside from the aforesaid objects this invention resides in the provision of a portable shower bath consisting of certain elements adapted to form a receptacle in which to pack certain other elements thereof.

In addition to the above mentioned objects this invention resides in the particular construction of the water heating unit and association thereof with the water supply reservoir and other adjuncts thereof.

Among the many objects of this invention is the provision of means whereby certain elements are constructed for interchanging.

With these and other objects in view this invention resides in certain novel features of construction and arrangement of elements to be hereinafter. more particularly set forth in the specification, illustrated in the accompanying drawings and pointed out in the appended claims and, while this disclosure depicts my present conception of the invention, the right is reserved to use any suitable material and resort to such changes in arrangement and construction of parts as come within the scope of the claims.

In the accompanying drawings forming a part of this application:

Figure 11 is a detail perspective View of one corner of the duck-walk as assembled in Figures 9 and 10.

In these drawings, the letter A indicates a tower for supporting a water tank T, the legs of the tower being formed ofangle iron sections I, which are detachably connected together. by the members), as shown in Figure 6. The legs are perspective view of one braced by the brace bars3, which have the slots 4 in their ends for engaging, in a removable manner, the studs 5 on the legs. The brace bars are pivotally connected together in pairs, at their centers as shown at 6. Feet 1 are secured to the lower ends of the legs. The frame at the top of the tower is shown at 8 and is formed of angle iron and it is braced by the bars 9 and sockets Ill are formed at the exterior corners of the frame 8 for receiving the upper ends of the legs I and the parts are held together by the cotter pins H, see Figure 4. The tank 5 seats on the frame 8, as shown in Figure 1.

A stove, in the form of a cylinder l2, has its open bottom seated on a frame 13 made in the form of a cross, see Figure '7, each bar of the frame being of inverted T-shape, with notches It in the ends of the bars for receiving parts of the lower end of the cylinder l2. This frame holds the cylinder off the ground so air can enter the same to support combustion. A cylindrical boiler 15 passes through the stove and projects from the upper end thereof and has its lower end seated in a recess formed by the long notches 16 in the central parts of the bars of the frame H. A spider l! spaces the boiler from the upper part of the stove and a hinged sectional cover I8 is provided for the top of the stove, the cover being of substantially conical form and when closed its top is spaced from the boiler, as shown in Figure 1, so the products of combustion can escape. A pipe line [9, containing a valve 2|], leads from the tank to and through the top of the boiler, and to a point adjacent the bottom of the boiler for leading water from the tank to the boiler. A hot water pipe line 2| leads from the boiler, across the tower and connects to a water head 22 supported on the brackets 23 attached to the legs at one side of the tower. Spray pipes 24 curve downwardly and outwardly from the water head 22. The lines l9 and 2| extend parallel to each other and they are connected together under the tank. by the coupling 25 containing a valve 26, so that by adjusting the valve, cold water from pipe H! can be mixed with the hot water flowing through pipe 2| so as to make the water flowing from the nozzles of the proper temperature. Other valves can be placed where ever desired to properly control the flow of water from the nozzles. Also a short length of pipe 21 containing a valve 28 is connected to a part of the hot water pipe, for furnishing hot water to other ports or devices.

The persons taking the baths stand on a sectional platform 30 which is composed of a pair of beams 3| and spaced cross strips 32. Alternate strips are made longer than the other strips 50 the ends of the long strips project beyond the ends of the short strips, as shown in Figure 2. The platform is made up of four sections and each of a length that it can be placed on 'a member of the frame 8 and when these sections are placed on the frame I to form a rectangular box or crate the projecting ends of the long strips 32 of one section will overlap the ends of short strips of the next section as shown in Figure 11.

Thus when the apparatus is to be stored or shipped the legs of the tower are taken apart and from the frame and some of the sections of the legs are placed in upright positions with their lower ends in the sockets Ill and held therein by the cotter pins. Then the fourv sections .of the platform 30 are placed in the space formed by these legs with their ends abutting, as shown in Figure 11. The heater and boiler are placed in the tank which is on the frame 8 in the bottom of the crate formed by the legs and the sections of the platform. Then tie rods 35 are placed across the top of said crate with their ends passing through holes in the upper ends of the legs, said ends being threaded to receive the nuts 36, as shown in Figures 9 and 10. The other parts'of the apparatus, such as the pipes, braces, etc. are placed in the crate in the spaces left by the other parts. Thus'the parts of the entire apparatus are packed in a small space so the device will not take up much room when stored or shipped. The parts can be easily and quickly assembled and set up and when so set up the device will furnish water of the desired temperature and several men can take shower baths with the least effort.

It is thought from the foregoing description that the advantages and novel features of the invention will be readily apparent.

What I claim and desire to protect by Letters Patent is:

1. A collapsible tower for bathing apparatus comprising a rectangular top frame of angle iron having vertical and horizontal flanges with the latter extending inwardly from the upper parts of the vertical flanges, brace bars connecting the adjacent sides of said frame to form a tank supporting means with the horizontal flanges of the top frame preventing lateral movement of a tank seated on the brace bars, socket forming members at each corner of the top frame each consisting of an angle member having ribs at the free edges of its flanges resting against the vertical flanges of the top frame, downwardly diverging sectional angle iron legs having their upper ends received in the sockets, removable pins holding the upper ends of the legs in the sockets, pairs of leg brace bars for said legs, each of said leg brace bars extending from the lower part of one leg to the upper part of an adjacent leg and having a key-hole slot at each end and, each pair of leg brace bars intersecting and being pivotally connected at its joint of intersection, and studs carried by said legs and engaging in the key-hole slots.
